Arabidopsis..the 'Flagship Model' of the plant world..

How a humble weed became a superstar of biology Arabidopsis thaliana was always an unlikely candidate for the limelight. But 25 years ago, the diminutive thale cress launched the botanical world into the molecular era.

Hydathodes at the forefront of plant immunity against vascular pathogens Hydathodes are tiny plant organs that form an interface between the leaf surface and xylem vasculature. They facilitate excretion of xylem fluid under…

We wrote a review 📖 on hydathode immunity! Learn how bacteria exploit hydathodes to access the vasculature and open questions for future research.

Mobile transcriptional regulators DELLA and SHORT-ROOT control the number of root inner cortex cell layers able to host symbiotic AMF.

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Localized glutamine leakage drives the spatial structure of root microbial colonization Plant roots release exudates to encourage microbiome assembly, which influences the function and stress resilience of plants. How specific exudates drive spatial colonization patterns remains largely ...

Marker-assisted in vivo imaging reveals pre-patterning events prior to lateral root organogenesis The branching pattern of the Arabidopsis root is established as early as in the distal tip of the primary root.

Looking for some clarity in the labyrinth of terms regarding lateral root initiation (priming, founder cell specification, pre-branch sites, oscillation zone, root clock,...)? Here is our new paper hopefully bringing some light in the darkness:

Hormonal regulation of cell fate plasticity of xylem-pole-pericycle lineage in Arabidopsis roots In Arabidopsis roots, xylem-pole-pericycle (XPP) cells exhibit dual cell fates by contributing to both lateral root (LR) and cambium formation. Despit…

🌱 What happens when lateral root primordia (LRPs) fail to emerge?
Using our new lineage tracing tool LRTracker, Xin discovered that arrested LRPs don’t just disappear—they gradually switch fate and become part of the cambium, contributing to secondary growth.1/x

Constraints on chromosome evolution revealed by the 229 chromosome pairs of the Atlas blue butterfly The genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.

Friday Flower 001: Mimulus lewisii 🌸✨

Monkeyflowers are masterpieces of design with nectar-guide spots formed by an activator–inhibitor system of MYB transcription factors. These generate reaction–diffusion patterns across the ventral petal.
